The present invention N relates vto 'iinprofve-y niente' in coin controlled vending machines.y More especially theinvention relates 'to in eans for' preventing the Er'eniovalfvof goods froniacoin' controlled vending apparatus by v ineansof .false'coins of a lowerw'eight than thel genuine "coins for which' Ithev inachine is In accordance with theinvention an ejectingdevice is provided,v 'b yjnieans of which 'false coins of'cardboard, pressed goods, fibre, light metal, sheet'Vnietaljetc.,y of less Weight than the genuine coins required, are stopped,

caught and ejected. For this purpose the 511;. coin conduit is equipped with a device 'which is arranged at the' end 'of a balanced testing lever and which initially catchesall f coins falling through the said conduit. It 'a coin has the prescribedweightfit will rock the said device out oi the coin conduit andfthecoin 'will then drop into operative position., If however a false coin of less weightthan prescribed is inserted into the apparatus, the weight ot such coin will not besufiicieiit to inove theca'tchingrdevice out tei'iwill slide over an inclined face arranged von the catching device andffbe.v ejectedv Fig', 'l isa sectional view `through the'. inletv` f; `':hu'te orconduit. of the'coin? with the other @mechanisms removed; 1
